These mosaic lines in the Chinese desert were first discovered by Google Maps, but their purpose remains a mystery. According to some reports, the lines were built in 2004 as a military target exercise base, but claims of such a purpose have not been formally confirmed.

. China's mosaic lines, Gansu Province

These mosaic lines in the Chinese desert were first discovered by Google maps, but their purpose is still a mystery. According to some reports, the lines were built in 2004 as a military target exercise base, but claims of such a purpose have not been formally confirmed. Some people think these lines are a symbol or image to allow UFOs to be seen from space orbit , similar to the statement about NASCAR line in the Atacama Desert in Peru.

.Lauradov Stone Disc

Lauradov Stone Disc is a 12,000-year-old stone disc found in Nepal . It clearly shows the image of a disc-shaped UFO, which seems to have an alien in the spinning galaxy. , which believes in other forms of life, has been recorded in ancient Egyptians, but there are almost no records to prove that other ancient cultures also believe in alien forms of life. This may be a sign that aliens are not something invented in modern times, but a congenital fear that has been harbored since our human origin .

. Mayan pyramids, Teotihuacan, Mexico

Mayan is an ancient Central American civilized population known for its brilliant temples and encounters with Spanish colonists. The Mayans were very religious and believed in the sacrifice of living people, and recently, researchers noticed that their temples were still built with expensive, shiny materials called mica. In modern times, mica is used for energy and technology production, and the question is whether the Mayans know its energy and purposefully construct secret energy sources in case the city is broken. Most likely, the Mayans did not know that these micas could produce energy, and the reason why they used this material was just for their shiny and dazzling texture.

30 million years of screws, Russian

998 found something like a screw in a 300 million year-old rock near Moscow, which became another strange mystery that investigators have not yet solved. This screw is clearly visible in the rock, which dates back 200 to 300 million years ago, and before that there was no intelligent life form on Earth. Although the screws may have been embedded in the rocks later, this geological event has not been confirmed, meaning that the 300 million-year-old screw found here remains a mystery.

. Sliding stones, Death Valley National Park, California

These rocks, considered "sailing stones", lay in the "runway basin", a dry lake in the National Park, which is very flat and 2.5 miles long north and south. Scientists tried to explain how these stones crossed the flat lake bottom, and they raised various speculations such as strong winds to UFO activity. However, recently, the mystery was unveiled by Ralph Lorentz, a scientist at NASA at NASA, who discovered that in winter conditions there is enough water and ice to allow the rock to float along the muddy bottom of the "runway basin" and leave traces as the rock moves.

6. The ritual center of Nabtagan Lake, Egyptian

Nabtag is located in the Sahara Desert in Egypt. This site contains the earliest known as astronomy arrangements in the world, a thousand years earlier than the English Stonehenge . Although civilization finally appeared in the arid area of ​​the Nubian Desert from the 8th to the 10th centuries BC, the stone site remained next to this seemingly ancient lake. Today the desert is completely dry, but about 130,000 to 70,000 years ago, there was evidence that the desert had the last moisture at that time, and it was very likely that a lake was formed near the ancient sacrificial sites. While the origin of the site is not necessarily a mystery, it is interesting that Stonehenge in England is often considered the original astronomical site, while Nabta was a thousand years earlier.

7. Unexplained stone doll, Nanpa, Idaho

This stone doll was discovered during a drilling operation in Nanpa, Idaho in July 1889.The doll is obviously made of human hands, but it was found to be 320 feet deep, and it is much earlier than when humans began to live in that part of the world. Some people believe that the doll was buried by aliens, and it is also possible that the doll has become deeper and deeper as time goes by. The doll itself may not be a mystery, but how it sinks so deep underground is undoubtedly puzzling.

8. The puzzling wedge, Transylvania

This aluminum wedge was discovered on the banks of the Muresh River in Transylvania in 1974 and buried in the remains of mastodon for 20,000 years. Judging from the shape of its shell, the aluminum wedge itself is considered to have been around 300-400 years. Normally, aluminum is always doped with other metals, but in this fantasy, this aluminum wedge is made of pure aluminum, which is too interesting because aluminum was only discovered in 1808 and only produced high-quality aluminum in 1885. So, where did they get aluminum, or could there be more than one great mind coming up with a recipe for making aluminum?

9. Fossil Giant, Ireland

This petrified giant was discovered in Ireland during a mining operation in 1895. The strange giant is 12 feet tall, with arms and legs 4 feet long, and the strange giant has six toes on one of its feet. His appearance reminds many people of a sentence written in 2 Samuel, "I was fighting in Gat again. There was a tall man with 6 fingers on each hand and 6 toes on each foot, and a total of 24 fingers. He was a natural giant."

0. Dog suicide bridge, Scotland

This Owalton Bridge was built in 1859. It is famous because a large number of dogs jumped off the bridge and "inflicted suicide". The suicide of dogs on the bridge was recorded in the 1950s and 1960s, and suicides continue to occur today. Yet there is little evidence that dogs are really capable of conducting and understanding suicide, suggesting that near the bridge it is possible that a scent induces dogs to dare to leap like this regardless of such heights.
